I was told that if there is condensation in a closed plastic container it can be poisonous. I have no idea where the person got the idea and they seemed, to me, to be a total hippie (like zelos :P). I tried looking it up and can't find anything. They brought it up when buying a pie that had some condensation in the container because it had been previously frozen. They almost didn't buy it. I can't think of any reason why condensation would be poisonous because of plastic.
Has anyone heard of this or is this person just completely crazy?
